With the previous commit, this should no longer be possible, but
otherwise we got report of a panic when accessing the mirror configuration.
The following test would be able to produce the panic:
```
s := RunBasicJetStreamServer()
if config := s.JetStreamConfig(); config != nil {
defer removeDir(t, config.StoreDir)
}
defer s.Shutdown()
nc, js := jsClientConnect(t, s)
defer nc.Close()
_, err := js.AddStream(&nats.StreamConfig{Name: "SOURCE"})
require_NoError(t, err)
cfg := &nats.StreamConfig{
Name: "M",
Mirror: &nats.StreamSource{Name: "SOURCE"},
}
_, err = js.AddStream(cfg)
require_NoError(t, err)
err = js.DeleteStream("SOURCE")
require_NoError(t, err)
cfg.Mirror = nil
_, err = js.UpdateStream(cfg)
require_NoError(t, err)
time.Sleep(5 * time.Second)
```
Again, now that we reject the mirror config update, the panic
should no longer happen, but adding preventive code in case we
allow in the future.

Tests
Tests that run on Travis have been split into jobs that run in their own VM in parallel. This reduces the overall running time but also is allowing recycling of a job when we get a flapper as opposed to have to recycle the whole test suite.
JetStream Tests
For JetStream tests, we need to observe a naming convention so that no tests are omitted when running on Travis.
The script runTestsOnTravis.sh will run a given job based on the definition found in ".travis.yml".
As for the naming convention:
- All JetStream tests name should start with
TestJetStream - Cluster tests should go into
jetstream_cluster_test.goand start withTestJetStreamCluster - Super-cluster tests should go into
jetstream_super_cluster_test.goand start withTestJetStreamSuperCluster
Not following this convention means that some tests may not be executed on Travis.
